Of course, restraunts should charge for water
Braum's charged me 25¢ for a cup of water. Well, its about time. I often just get water to drink with my meals when I eat out and restraunts should charge me for a glass/cup of water. (Note: that's how I spell restraunt. Some more examples of better spelling.)
Some argue that water should be free cause, well, it's water. Maybe the water should be free (even though every place serving water has to buy it from the local water utility), but who should pay for the other costs involved - the glass or cup, the ice,
the straw, the lemon, and the soap (and water) to wash the glass? Those that buy the other drinks? Should they pay for the 'free' water? It seems very reasonable that the water-drinking customer should help cover the costs for these items. It just seems fair.

Implementation of the fee
$1.00 seems too excessive and unreasonable. 25¢ or 50¢ seems reasonable. Enough to not be a burden, but enough to offset the costs.
In the examples above, the charges ranged from 20¢ to 50¢.
An individual restraunt would, understandably, be hesitant to charge for water if its competitors don't. The key to successful implementation is for an entire group of restraunts to add the charge. This could be an association, like the NRA, state and city associations, or community restraunt groups.

Advantages
Charging a small fee for a glass or cup of water is:
• Fair
• Economically appropriate
• Eco-conscious: discourages water waste.

From a food blog
Why do European restaurants charge for tap water?
Because it's not free. It costs to wash the glass, then there's the ice used, electricity, the dish machine, and the water billed by the month as a utility; the server cost money to pour it, deliver it, and clean up after. In all restaurants there are the unrecoverable expenses caused by just having a person walk in the door. Things like toilet paper, soap, paper towels, rags used to wipe the table they sat at - even if all they had was a glass of water. All these things add up. Those are courtesies, but, the cup/glass of water is a tangible consumable that is part of the meal as is tea, coffee, or soda. The fact is, water isn't free.
We pay nothing for a cup of water but about 2 bucks for soda and the only difference is a small bit of flavoring.
Why should we expect others to subsidize our choice of drink? Of course we should be charged for water. www.jamesrobertwatson.com/chargeforwater.html
